GENERAL DESCRIPTION
The Model 4503 is a remotely controlled (GPIB) AC voltage reference system for applications with automatic test equipment.  It is a highly versatile reference source, designed to meet the needs of  computer system production line testing, ATE systems and standards laboratories.  The unit is also  calibrated with equipment traceable to the National Institute of Standards & Technology.  The 4503  is overload and short circuit protected and is fully operational in normal environmental conditions.

SPECIFICATIONS

OUTPUT
Amplitude (True rms) Ranges and Resolution:

Amplitude Accuracy:

Basis for Accuracy Statement: The statement includes all peripheral, additive specifications (errors for line and load changes, ambient temperature changes and stability are included in the accuracy statement and are designated “non-additive”). Thus, this instrument may be used under minimally controlled environment and unmonitored conditions.

NOTE: All specifications, including accuracy, are valid and warranted for twelve months.

Harmonic Distortion and Noise (band-pass 10Hz to 1MHz):

Compliance Current (Loading): 10mV and 100mV range, Z_out = 10W (into loads >5kW); 1V, 10V and 100V range, 10mA.
Load Regulation (non-additive, no load to full load): 10mV and 100mV range, not applicable; 1V, 10V and 100V range, <10kHz 0.005%, >10kHz 0.01%.
Line Regulation (non-additive): ±0.001% of setting for 10% line change.
Stability (non-additive): 24hrs., 0.005%; 1 month, 0.007%; 6 months, 0.01%.
Temperature Coefficient: Ambient, 0.005%/°C; operating limit, 0.007%/°C.

FREQUENCY SPECIFICATIONS

Frequency Accuracy (Crystal Controlled): 0.001% of setting.
Frequency Stability: 24 hrs., 0.0005% of setting; 1 month, 0.0008% of setting; 6 months, 0.001% of setting.
TTL Compatible (Squarewave) Output: This is an auxiliary output, synchronous with the sinewave output. Output will drive 10 TTL loads.

PROGRAMMING
Manual Control and Display: All functions may be controlled manually (“local”). A single front panel switch controls the “remote/local” mode without disconnecting the program lines. The 4503 will continue to accept and store all up-dated program commands while set in the “local” mode. The displays indicate the status of the instrument in either the “local” or “remote” modes depending on the mode selected.
Remote Programming Subsets (IEEE-488.1, GPIB Interface): SH1, AH1, T6, L4, SR1, RL0, PP2, DC0, DT0 and E1.
Programming Format: Integrated microprocessor GPIB interface.
